r 4 Claims 01. 298 -9) This invention relates to automotive vehicles and more particularly to a concrete buggy.

.It is the primary object of this invention to provide aconcrete buggy in which concrete is transported to a dumping location, in which the dumping operation will ein ty an portion of the concrete contained in the bucket on the buggy and will stop and hol'd the bucket in any position from the lower to the fulldurnpin'g point. Also, with the cement buggy of the present invention, the dumping operation can be accomplished from a number of different positions respect to the longitudinal center line of the buggy. That is, the concrete may be dumped forwardly of the buggy, to either the right or left hand side of the buggy, or at points intermediate the forward and side positions. y

With the above objects in mind, it will be apparent that by the employment of the concrete buggy or the present invention, it will be possible to drive parallel to a concrete form and dump a continuous stream of concrete into the form, and by controlling the amount of concrete to be dumped, the form may be finished up "2,887,339 Patented May 19, 1959 from the front end 24 of the frame, the upper surfaces of the respective running boards may be suitably roughenecl to provide a non-skid surface and they are preferably made or a structural metal. The name is mounted u on pneumatically tired wheels including a j single rear guiding wheel 26 rotatably mounted on tapered roller bearings contained within the pivot hearing hohing 28 and operatively connected to the steering wheel 30 mounted at the top of a vertical steering column 32, the steering column and steering wheel are disposed centrally of the frame and immediately to the front or 34 and 36, hence making these wheels the driving wheels of the concrete buggy.

The front end 24 of the frame member 10*, includes a pair of spacedparallel longitudinally extending channels Si and 11, and disposed immediately over the differ enti-al housing 40 is a platform bearing support plate to the grade nails, that is the last two inches approximately, thereby saving the time required to bring eonoreteup to the finish grade in the old way, that is by continuously returning to the initial dump point and adding sutficient concrete to bring the level otthe concrete' in the form up to the finishgrade.

Gther objects and advantageswill becoinewapparent from the following detailed description, forming the specification, and taken in conjunction with the accompanying drawings, wherein:

or beam 42 resting upon the top surface of the 9 and 11 and extending therebetween and secured thereto byeii suitable means such as welding, the plate 42 de; fining a bed plate. The bed plate or beam 42 arries centrally thereon an upstanding hollow column 44 provided with a bearing race 46 at its upper end in the bore 48 thereof. An internal annular flange formed integrally with the column 44 extends laterally from the interior wall of the bore 48,- as shown in Figure 5', to define a stop for the bearing 52 which carries stein or stub shaft 54. The hearing 52 being received in the race 46 so that the bearing is carried by the column 44; Th stem 54 is provided at its upper end with. the peripnerai, outwardly extending collar 56 which acts as a stop for the upper end of the bearing 52.

Figure 1 is a perspective view or the concrete buggy or dump truck embodying invention; Figure 2 is atop plan view of the buggy shown in Figure 1; i Figure 3 is a side elevational view thereof;

Figure 4 is a cross sectional view taken on line 4-4 of Figure 3; v v i V Figu're 5 is a cross sectional view taken on line 5-5 of* Figure 4; and a I Figure 6 is a diagrammatic showing of the hydraulic The stem 54 carries at its upper end a platform 58 and the platform 58 is secured upon the upper end or collar 56 of the stem 52 centrally of the platform on its lower face so that the platform 58 is rotatably mounted for movement in a horizontal path about the vertical axis of the column 44.

. in the same plane as the lower or bottom surface of the system whereby the double-acting hydraulic cylinders M With continued reference to the drawings, were is shown an automotiveconcre'te buggy or dump truck, a structuralframe' 10 uponwhich is mountedat one end thereof, a seat 12 upon apair of spacedtubular standards1-4-with a tool box secured at the lower ends orthe standards 14 and extendingtherebetween and outwardly therefrom, the tool box be'inglidentified bythe reference numeral. 16; The frame 10 also supports an engine,

generally indicatedatlS, which maybe (if the air-cooled type, The metal structural frame 10 hasalso provided connection therewith a pair of laterally extended flanges Y20 and 22 which define running boards onopposite sides of the structural frame member 10 and ex tend longitudinally thereof from .the back endpor the end which the "seat '12 is mounted, to a location spaced bed p1ate 42, and a washer or collar 62 is carried by the lowerend face of the stem 54 so that the washer 62 abuts the bed plate or beam 42 on its bottom surface, and the washer or collar 62 is secured removably upon this: end of the stem asby bolts 64 extending upwardly through the washer collar 62 and into the lower end face of the stem54 in suitable threaded apertures provided therein. Thus, it will be seen that the stein or stub shaft 54 is prevented from having undesirable longitudinal movement or end play within the support column 44.

-The platform 58 which is rotatably carried by anti-friction bearing 52 for rotational movement about the vertical axis of the support column 44' actually dc fines a turntable. Mounted on the anti-friction bearing 52, which is shown as being a tapered roller bearing'so that upon removal of the collar or washer disc 62, the

stem, 54 may. be lifted out of the support column 44; H A pair of spaced, parallel mounting lugs 66 and 68 extend upwardly from the turntable 58 adjacent thefront edge 70 thereofand at opposite sides thereof. ,T emoantinglugs 66 and 68 are somewhat arcuately formed so as to have their upper ends extend forwardly of the front edge 70 of the turntable 58, and the upper end of each of the identical mounting lugs 66 and 68 is provided with a suitable aperture therethrough. A concretebucket 72 having an open top 74, the forward end of which is somewhat convergent to define a funnel-like discharge, is mounted upon the lugs 66 and 68 and extends therebetween, the bucket 72 being so mounted as to be movable in an arcuate path about a horizontal axis provided at the upper ends of each of the mounting lugs 66 and 68. The particular manner in which the bucket is mounted upon the mounting lugs is clearly shown in Figures 1 and 3 where it will be seen that a mounting plate 76 is secured on either side of the concrete bucket 72 as by beingw'elded thereto and has integrally formed at its upper 'end an L-shaped car 78 having the shorter leg thereof extending laterally and outwardly from the side at the lower end of the latch 90 as by a nut 98. The other end of the rod 96 remote from the latch arm 90 is secured at one end of a bell crank 100 pivotally mounted as at 102 upon a bracket secured on the flange or running board 20. The other end or arm 104 of the bell crank 100 carries at its end remote from the pivot point 102 a foot pedal 106. Upon depressing the arm 104 so that it rotates in a clockwise direction about the pivot 102, the rod 96 will be moved rearwardly, that is toward the end of the buggy remote from the turntable, which in turn will cause the latch arm 90 to rotate about the pin 94 in a clockwise direction and against the tension of a spring a 108 so as to disengage with the selected notch 88.

of the concrete bucket upon which it is mounted, and the longer leg thereof extending downwardly generally parallel to and spaced from the associated mounting plate 76 soas to define a mounting lug receiving socket which is arranged to fit over the upper end of a mounting lug, either 66 or 68 depending upon which side of the bucket the ear is mounted. Each car 78 is provided with an opening or aperture centrally therethrough adapted to register with the aperture provided adjacent the top of each of the mounting lugs so that a pin 80 may be inserted into the registering openings or apertures to rotatably mount the concrete bucket 72 upon the mounting cars 66 and 68, so that, in effect, the concrete bucket 72 is rotatably mounted upon the turntable 58 and is rotatable about the pins 80 as an axis in an arcuate path perpendicular to the path of movement of the platform 58. Thus, the concrete bucket 72 will be rotated as the turntable is moved in its arcuate path since the bucket is carried upon the turntable. The rotation of the turntable 58 and the bucket 72 along therewith is accomplished manually and is capable of being secured against further rotation in a plurality of positions, which are roughly, where the convergent sides define a chute or funnel-likedischarge exit 82 which will be so disposed as to be along the longitudinal center line of the concrete buggy frame or in the straight ahead position; or the discharge exit 82 may be disposed right angularly to the, longitudinal center line of the concrete buggy frame to the right side thereof as shown in broken lines in Figure 2 which will be the right side position; or the bucket may be similarly rotated to the left hand side of the concrete buggy by rotation of the turntable in the counterclockwise direction; and also, the bucket may assume a position to the right and to the left of the straight ahead position but intermediate the right and left hand positions respectively. In order to lock the turntable in the desired angular, rotated position with respect to the longitudinal center line of the concrete buggy frame, the angular relation being'especially relative to the position of the concrete bucket 72, a, depending annular flange 84 is carried by the bottom surface of the turntable 58 so as to be concentric with the vertical axis of the support column 44 and spaced outwardly therefrom. The free edge 86 of the flange 84 is provided with a plurality of recesses or slots 88 spaced equally from each other about the periphery of the flange 84, and more specifically, each recess or slot 88 being angularly spaced at 45 intervals. Five such slots or recesses are provided. The flange 84, it will appear, defines a lock collar. A latch arm 90 is pivotally mounted intermediate its ends upon a bracket 92 secured upon the frame 10, the pivot being defined by a pivot pin 94. The upper end of the latch arm 90 which projects above the top of the bracket 92 is adapted to engage into selected ones of the slots 88 to thereby prevent rotation of the turntable 58 about its vertical axis.

Arod 96 has one end thereof pivotally. connected The spring 108 is connected at one end to the latch arm 90 intermediate the ends of the arm, and is secured at its other end upon the rod 96 a short distance from the point of connection of the rod 96 to the latch arm 90. The spring 108 is so tensioned as to normally maintain the latch arm 90 within the selected recess or slot 88. However, the depression of the foot pedal 106 and the resultant clockwise rotation of the latch arm 90 will further tension the spring 108 in such manner that upon release of the foot pedal 106, spring 108 will tend to rotate the latch arm 90 about its pivot pin 94 in a counterclockwise direction. Thus, the concrete bucket 72 may be manually rotated along with the turntable 58 so as to assume any of the previously described positions with respect to the longitudinal center line of the buggy itself, and be locked in the desired position by operation of the latch arm 90 being received within the selected one of the recesses or slots 88 in the lock collar 84 corresponding to the desired position of the concrete bucket 72 with respect 6 to the longitudinal center line of the concrete buggy.

In addition to the rotation of the concrete bucket 72 upon the turntable 58 to a selected angular position, bydraulically operated means whereby the concrete bucket 72 may be rotated about the pins 80 in a vertical path perpendicular to the horizontal path of movement of the bucket upon the turntable 58, is provided. More specifically, the means whereby the concrete bucket 72 may be rotated in a vertical plane about a horizontal axis so as to dump the concrete contained within the bucket at any given point and at the selected angular relation to the longitudinal center line of the concrete buggy, includes a pair of double-acting hydraulic cylinders 110 and 112. One end of each of the hydraulic cylinders is pivotally mounted upon an upstanding plate-like ear or lug 114, the end to be secured thereon is provided with a transverse groove 116 into which groove the ear or lug 114 is received, and the lower end 118 of each of the hydraulic cylinders is thereby secured upon the turntable 58 upon which the ears 114 are secured, by having a bolt and nut passing through the respective ear or lug 114 and the groove 116 so that the lower ends 118 of each of the hydraulic cylinders may move in a vertical path about the respective ears 114 as an axis. The upper end 120,

, which is actually the cylinder rod telescopically received within the respective hydraulic cylinders and movable longitudinally of the cylinder in response to hydraulic fluid pressure, is secured adjacent the upper edge of the concrete bucket upon a mounting plate 122 by a pin or bolt 124 so as to be pivotally mounted at this point.

The operation of the double-acting hydraulic cylinders and 112 is controlled by the operator by movement of the control valve handle 126 which is externally mounted upon the hydraulic fluid control valve housing 128 carried on the steering post column 32. This will permit hydraulic fluid pressure generated by the pump 130 to flow to the cylinders. The pump 130 is opera: tively connected to the engine 18 through a pump clutch contained within the pump clutch housing 132. The housing mounts a clutch shifting lever 134 externally thereon to transmit the power from the pulley 136 which is asszsse driven by a pulley belt 138 connected between the driven pulley 136and the engine drive shaft 140.

The pump 130, whenplaced inoperation by movement of. the clutch shifting lever 134 in the proper direction, will draw the hydraulic operating fluid from the hydraulic fluid reservoir 142, so as to be drawn into the control valve 129 contained within the housing 128, so that upon movement of the control valve handle 126 in a clockwise direction, the hydraulic fluid will be forced through flexible line 144, which branches as at 146 into two other fluid conduits 148 and 150, which enter the lower ends of the respective double-acting hydraulic cylinders 110 and 112 as at 152 and 154 respectively. Two branches or branch conduits 156 and 158 are connected at one end to the upper end ofthecylinder portion of the respective hydraulic cylinders 110 and 112 as at 160 and 162 respectively todefine return lines which merge into a single return line or conduit 164 as at 166.

.The return line 164 is connected into the two-way valve 129 and continues to enter the reservoir 142 as at 168.

Hence, it will be seen that upon movement of the control valve handle 126 in a clockwise direction, hydraulic fluid will be forced from the reservoir 142 by action of thecpump 130 to flow into the flexible line or conduit 144 and thence through the branch lines 148 and 150 to enter the lower ends of the cylinder body portions of the the respective cylinders 11.0 and 112 so as to impinge or exert pressure upon the piston 119 in each of the respective cylinders to thereby force the fluid on the other side'of the pistons 119 out through the return branch lines 156 and 158 and into the return conduit 164 and back into the reservoir 142. This will force the piston rods 120 in each of the hydraulic cylinders to move outwardly longitudinally of the cylinder body portion of each of the hydraulic cylinders, and since the upper end of each of theipiston rods 120 are pivotally connected upon the concrete bucket 72, the concrete bucket will be forced to move in its vertical path about its horizontal axis provided by the pins 80 and dump the contents of the concrete bucket. It will, of course, be realized that the amount of movement of the bucket 72 in its vertical path about its horizontal axis may be readily controlled by cutting off the flow of hydraulic fluid into the line or conduit 144 by movement of the control valve h-andle 126 to a position where fluid will no longer be enabled to enter intothe flexible line or conduit 144. Further rotation of the concrete bucket 72 about its horizontal axis may be accomplished in the dumping direction by further causing elevation of the piston rods 120 so that any amount of the concrete or other material within the bucket 72 may be dumped at any location, or all of the material within the bucket may be dumped at a single location. The direction of flow of the hydraulic fluid in the dumping operation is shown by the arrows in the diagrammatic sketch of the hydraulic fluid system shown in Figure 6.

To rotate the bucket 72 from a dumping position, shown in broken lines in Figure 3, to an upright position, as shown in solid lines in Figure 3, the control valve handle 126 is moved from its neutral position, in full lines in Figure 3, in a counterclockwise direction so that the two-way valve 129 will cause the hydraulic fluid from the reservoir 142 to flow into the return conduit 164. The fluid will then flow into the return branch conduits 156 and 158 so that the fluid will be under pressure by action of the pump 130 and will enter the piston cylinder portion of each of the hydraulic cylinders 110 and 112 to thereby cause the piston 119 in each of the cylinders to move toward the lower end thereof and force the fluid in that end of the cylinder out through the lines 148 and 150 and through the line or conduit 144 and then through the two-way valve 129 so as to by-pass the pump 130 and flow into the return line 164 and thence back into the reservoir 142. In effect, in the return of the concrete bucket 72 to its initial position, as shown in full lines in Figure 3, from the dumping position as shown in full lines in Figure .1 and in broken lines in Figure Sp-the respective linesorconduits148 and 150 and anportlonmf the line or conduit 144 act in the nature of a return' line.

From the foregoing, it will be readily apparent that the concrete buggy of the present invention includes means whereby the concrete bucket or container 72 may be selectively rotated about the vertical axis and in a horizontal plane so as to have its discharge end angularly disposed with relation to the longitudinal center lineof the automotive concrete truck or buggy. Also, in :addition to the selective angular position of the materialcontaining receptacle 72, means are provided whereby the material-containing receptacle 72 may be moved or rotated in a vertical arcuate path about a horizontal axisperpendicular to the vertical axis of rotation of the means whereby the bucket 72 may be angularly disposed, and'the means which causes dumping of the material within the bucket is hydraulically operated by "the operator of the vehicle from a location adjacent the steering column 32 upon which the control valve housing 128 is secured as by welding. Also, the means for causing the material within the bucket to be dumped therefrom is operatively connected to the engine 18 of the concrete truck or bucket inthe manner hereinbefore described. a

In operation, it will be evident that the concrete truck or buggy embodying this invention will be capable of dumping the concrete straight ahead, to either side at a ninety degree or right angular location or. position with respect to the straight ahead position and at a dumping position of the material-containing receptacle intermediate the straight ahead and the position to either side. Also, any portion of the contents of the receptacle mounted on the concrete buggy may be dumped at any given location. Or, with the bucket or receptacle 72 in one of the side positions,a longitudinally extending concrete form may be filled to the desired depth with'the material contained within the receptacle 72 as the concrete buggy or truck is moved in a direction parallel to the form. Thus, a later spreading operation to level off the concrete or other material dumped into the will be avoided, and excessive dumping of the material at any one location will be eliminated. I

Essentially, the present invention is in a concrete buggy or truck of the automotive type having an engine and a" frame with the turntable rotatably carried by said frame adjacent to one end thereof for movement in a hurtzontal plane about a vertical axis, a receptacle 72 carried upon the turntable 58 and mounted for rotation about an axis perpendicular to the axis of rotation of the turntable 58, and means, defined by the hydraulic system as shown in Figure 6, operatively connected to the, buggy engine 18 to move the container 72 about its axis" of rotation, In addition, the present invention includes means carried by the frame 10 to selectively lock the receptacle 72 in a given position of movement about its axis, this means being defined by the latch arm and the lock collar 84 with which it cooperates.
